As every leading lady in Hollywood already knows, the must-have fashion accessory for A-list feet is a pair of custom-made shoes by Christian Louboutin, who for $2,500 will create a mold of your foot to hand-craft footwear to your exact specifications — for an additional charge of $500 to $5,000 a pair.

But OK! has learned it’s not just the fashion-savvy adults of Tinseltown who’ve stepped into molds for Louboutin — even little Suri Cruise, at all of 18 months, has gone through the process.

A source close to the Cruise clan reveals to OK! that Suri’s mom Katie Holmes has already had her custom mold made (as has, ironically, Tom Cruise’s ex-wife Nicole Kidman), and come Christmas, thanks to executives at the company, so will Suri!

“She’ll be the youngest client,” a source tells OK!.
